Dual Laterolog to Array Laterolog - A New Method Based on Digital Focusing Coefficient

A new digital focusing method with different bucking coefficients is introduced, with no change in the conventional dual laterolog device, compared to the hardware focusing method. The conclusions can be achieve that using the new digital focusing method, we can get array measurement similar to the result obtained by array laterolog devices, on the other hand ,the error in hardware focusing method badly affects the measurement. This new method can be considered to be applied in the laterolog, with simple device which can save economy cost and be operated more easily.
